APPARATUS FOR GRINDING REVOLVING FLATS O F CARDING-ENGINES.

SPECIFICATION forming part of Letters Patent No. 501,995, dated July 25, 1893. Application filed October 13, 1890. Serial 110,367,970- tNo model.)

vented certain new and usefullmprovements in Apparatus for Grinding Revolving Flats of Carding-Engines, of which the following is a specification.

This invention relates to that class of carding-engines for carding fibrous materials preparatory to spinning, in which revolving flats are employed and is designed with the object of grinding the wire of the flats from their working surfaces without removing them from I 5 their position on the carding-engine.

The invention refers more especially to such grinding mechanism as have the working surfaces of the flats brought into contact with a horizontally moving bracket or slide which moves with them as they successively pass beneath the grinding roller while the grinding roller journals remain stationary.

It consists essentially of a sliding or moving block which moves along a slightly in- 2 5 clined path, by reason of being fitted with inclined slotsone at each end-mounted upon studs in a fixed or stationary bracket (or their equivalent) or which carries the flat in an inclined position as it moves along a true or spe- 0 cially formed surface against which the working surface of each flat successively bears and a small tumbler catcher pawl pivoted thereto which engages with the front edge of each fiat and causes the slide or block to be car- 5 ried forward therewith.

It will be fully described with reference to the annexed drawings wherein sufficient of a carding-engine is illustrated to show the working of the invention.

Figure '1. is a side elevation of part of the bend of a carding-engine and grindingbracket and roller with my invention in position affixed thereto';l3ig.lafront elevation of grind ing apparatus with the lower part of the card cylinder in section; Fig. 2. a front elevation of same with the bend in section; Fig. 2 a side.

elevation with roller bracket removed; Fig. 2 a side elevation from reverse side of bracket with. the flat in section; Fig.3. a side elevation: of the invention showing modified form of the sliding and stationary brackets; Fig. 4. a plan of Fig. 3; Figs. 5, 6, 7, side elevations of modified forms of sliding bracket; Fig. 8. a side elevation of pivoted lever which raises and holds the flats against the sliding bracket; Fig. 9. a plan of pivoted lever shown in Figs. 1, 2, and 8; Fig. 10, a side elevation of modified form of pivoted lever; Fig. 11. a plan of'pivoted lever as shown in Fig. 10; Fig. 12. an enlarged elevation of stud for the sliding bracket; Fig. 13, a transverse sectional elevation of bracket G and sliding bracket H on line :r0c, and Fig. 14, a transverse sectional elevation of same on line y-y.

The invention will be described with reference to one side only of the carding-engine and to asingle flat. It must however be understood that a similar appliance is attached to the other side of the carding-engine the two acting in unison and that the operation of grinding each flat in succession as they travel forward is the same.

' The flats A, the bend B, the flexible bend or disk B, the grinding roller 0, the grinding bracket D, the horned bracket E, over which the flats travel and the pivoted and weighted lever F which successively lifts up each flat while being ground may be of any ordinary or general construction.

To the grinding bracket D or to any other suitable fixing is-bolted or otherwise affixed a stationary bracket G preferably of the shape shown with two projecting horns g. A slide or moving grinding block or bracket H is mounted to slide to and fro on the horns g of the stationary bracket G preferably in a path slightly inclined to the horizontal the distance of travel to and fro being somewhat in excess of the width of a flat.

The slides I-I may be provided with slots h at either end and be carried on studs I screwed to the bracket G as shown in Figs. 1, 2, 2, 2 5, 6 and 7 or the ends of the slide H may be supported in slots formed in the ends gof the stationary bracket G as shown in Figs. 3 and 4:.

I prefer the arrangement whereby the slide H is connected to the fixed bracket G by the two studs or pins I" with anti-friction runners or bowls 'i which pass through the slots h at either end. The studs or pins I are screwed into the ends 9 of the stationary bracket G. They are of the form shown in detail in Fig. 12 with cheese-heads between which and the stationary bracket the grinding block 11 slides. The slots h in either end of the grinding block H are sufliciently long to admit of the desired length of travel and are inclined to a degree equivalent to or in flat A is brought to bear as it is raised by the pivoted lever F. 011 one side of. thegrinding block H is pivoted a tumbler or catch J against theend of which theedgeof the-flatcomes in contact as it moves forward. NVhen the flat has been lifted up against. the grinding block II and it has advanced until the side comes in contact with the tumbler J the two then move forward together .underthe grinding roller 0. The other end j of the tumbler J projects beneath the 'fixed stud I and being provided with an inclinedsurface when thegrinding block has moved agiven distance the endj is depresed and the .tum-i blerJ released from or moved out of contact with the flat A. lVhen the flat A is released by thewithdrawing of the tumblerJ and has been withdrawn from contact with the grinding block H, the block 1-] falls back to its firstposition to receive the next approaching flat by itsown gravity on account of the slots in the ends.

The upper surface of. the grinding block H is as shown curved to admit of the movement of an intermittent grinding roller-whensucli is used until the surface is below the level of the bend. or kneein the wire on the flat and the block II is further provided witha flange or feather extending downward to give it the necessary strength.

' In the inodificationshown in Figs. 3, 4, the grinding block H is provided with solidends which slide to and fro in the pivoted or swivel sockets I which are slotted as-shown to receive the ends. In this case the ends of the block H are inclined to givethe required in clination of movementto the grindingblock H;

In the modifications shown in Figs. 5, .6, 7 instead of an inclined movement beinggiven to the wholegrinding block H it is. caused to move in a plane tangential to the grinding roller G and on the under side the surface at it against which the WOI'kiDg surface a of the flat A bears is formed of a single incline, (as shown in Fig. 5,) a double incline h, (as shown in Fig. 6,) a curve or other suitable contour h" (as shown in Fig. 7) to give the required amount of heel or inclination to the wires of the flat as they pass beneath and are ground by the grinding roller 0.

The pivoted lever F which raises and holds the flat upagainst the grinding block II while being ground is pivoted on a studor short of the forms shown in Fig. 8 or 9. vicled-withan: adjustable stop to K relieve spindle f passing through a sleeve or bracket 6 attached to or forming part of the horned bracket E over which the flats slide. On its upper side is formed a face f upon which the flat rests and swivels when lifted up off the bracket E. The lever F may be either It is prothe grinding block H from any unnecessary weight and has also attached to it a finger or lug L with whichthe backs of the flats come in contact one by one as they travel to lift the weighted end of the lever and depress the 'the face f as'each successive flat is about to amount upon it.

In the modification shown in Figs. 10 and 11 a pivoted lever F is employed for the samepurposewithtavtop:face or surface f, an adjustable stop K? anda fingerL.

In operation the flats -will after being stripped ascend along the curvedtop of the ordinary horned bracket- E until they reach the end of the pivoted weightedwleverrF by which they are successively lifted .andtthe working surface a pressed againstthewprepared surface h or h of .the sliding. grinding block H. The tumbler-J engages with the frontredge of theflat .causingthetwoto travel forward together beneath the grindin g roller C and as they travel forward therinelination of the. slots "or endsof the. grinding block Hrgradually raises. itsothat it travels inta path inclined 'to the radius'of the. grindingroller Cand therebythe grindin g1is carried out to. give the required .heel or inclination to .thewireclothing of theflat; .or, as in.the.modifieationshownxin Figs. 5; 6,7, the flat itself. isinclined by hearing against a surface h" h""or h".ioflproper contour on the I under side of the. sliding grinding block I-I. When the required .distancehas been traveled. and the flatis clear of the grinding roller and the grinding completedthetumbler lis raised releasing the flat from contactwith. thegrinding block I-I while at the same time it dropsoif the surface f of the pivoted lever. F.
